Bug #2327: Cleanup Version: output of special agents

Date: 2016-02-10State: openClass: nastinessComponent: checks

Some special agents use the Version: field of the <<<check_mk>>> section for sendingtheir e.g. firmware version or something different. But this version is only meant forCheck_MK agent versions. So they should leave the field empty or provide the Check_MKversion.The special agents which currently have a version should still provide it e.g. in a separateagent section and have a check for it which at least displays this info.
